Abstract: A wireless device may receive, from a base station of a network, an indication of whether the network performs time traceability to coordinated universal time (UTC). For example, the indication may indicate that the network does not perform time traceability to UTC. Based on the network not performing time traceability to UTC, the wireless device may implement time traceability to UTC.

Abstract: An access and mobility management function receives, from a session management function, a request to set up a communication with a wireless device for transmitting downlink data. The access and mobility management function sends, based on the request, to the base station, a first paging message for a closed access group (CAG) wireless device that is allowed to access CAG cells. The first paging message indicates transitioning the CAG wireless device from an idle state to a connected state. The first paging message comprises a parameter indicating whether the wireless device is allowed to access non-CAG cells.

The NRF sends, to the AMF and based on the discovery request, a discovery response comprising the address of the SMF.

Abstract: A wireless device sends, to a network, a message indicating an enhanced steering of roaming (SOR) capability for network access information for one or more non-public networks (NPN). The wireless device receives, from the network, network access information comprising an identifier of a first NPN and a condition for whether the wireless device is allowed to access the first NPN. The wireless device sends, to the first NPN and based on the condition being met, a registration request message.

Abstract: A wireless device may communicate with a base station via a cell. A cell may be selected for wireless communications based on having a configuration that is capable of serving certain wireless resources associated with a wireless device. A wireless device may select a cell that comprises a communication link supporting certain wireless resources that may be required for use by the wireless device.

Abstract: A policy and charging control function (PCF) receives, from a session management function (SMF), a request for policy information of a wireless device, the request comprising a parameter of a time sensitive networking (TSN) bridge, wherein the parameter comprises port information of the TSN bridge. The PCF sends, to the SMF, a response to the request, the response comprising the policy information of the wireless device.

Abstract: A base station may communicate with one or more other base stations. A first base station may hand over one or more wireless devices served by its cell to a second base station (e.g., a neighboring base station), for example, to save overall energy consumption in the network. Feedback information (e.g., one or more messages) associated with performance of the second base station after the handover may be provided by the second base station to the first base station help further decision-making related to handing over other wireless device(s).

Abstract: A base station may communicate with other base stations for handover decisions. Information about energy consumption of other base stations may be used by the base station for efficient handover decisions. Predictions of energy consumption may be exchanged before making a handover decision so that handover decisions may be based on energy usage.

Abstract: An access and mobility management function (AMF) receives from a first wireless device a non-access stratum (NAS) message comprising an identifier (ID) of a group communication session. The AMF receives from a session management function (SMF) a message comprising a list of one or more second wireless devices associated with the group communication session and a list of one or more packet data unit (PDU) sessions. The AMF determines, based on a state of the one or more second wireless devices, to page the one or more second wireless devices. The AMF receives from the one or more second wireless devices one or more service request messages.

Abstract: A base station transmits, to a wireless device, at least one first radio resource control message comprising configuration parameters for a first session associated with a first session identifier between the wireless device and a user plane function and a second session associated with a second session identifier different from the first session identifier, for packet duplication of the first session, between the wireless device and the user plane function. The base station transmits, to the wireless device, at least one second radio resource control message indicating activation of the packet duplication.

Abstract: A method may include sending, by a wireless device to an access and mobility management function (AMF) via a first cell, a first registration request message requesting a network slice. The method may also include receiving, by the wireless device from the AMF, a first registration accept message. The message may include a network slice selection assistance information (NSSAI) indicating the network slice and may also include an indication that the network slice is rejected in a tracking area of a registration area. The method may further include, upon a cell change to a second cell, sending, by the wireless device to the AMF via the second cell and based on the indication, a second registration request message requesting the network slice. The method may additionally include receiving, by the wireless device from the AMF, a second registration accept message accepting the network slice.
